A series of Bering Sea storms will impact western Alaska this week, with elevated water levels, isolated coastal flooding, high surf, erosion, and strong winds. Heavy rain and snow are also expected for the West Coast into Interior Alaska. A multi-day flash flooding threat is forecast across parts of the southern High Plains and Southwest through the weekend. Surf remains high for Florida. Read More >

Environment
The following images are an analysis of the environment before and during the event. An upper level trough (Fig. 1) brought upper level support for a surface low moving through the forecast area. The warm front lifted northward through the night prior and early morning on 9/24/24, then the cold front swept through in the late afternoon and evening. Storms developed in the afternoon as skies began to clear (see radar/satellite section) and deeper moisture (PWATS, 850mb transport Fig.11) moved in with the front. Instability reached around 2000 J/kg surface based CAPE, with around 20-40 knots of bulk effective shear. In combination with low Lifted Condensation Levels (LCL's), it was a favorable environment for isolated strong to severe storms with tornadoes. The Storm Prediction Center (SPC) had our forecast area in a Marginal Risk for Severe Storms.
